'删除键' (shān chú jiàn) literally means 'delete key' — a standard key on computer keyboards and mobile devices used to remove selected text, files, or other digital content. The character 删 (shān) means 'to delete' or 'to erase', 除 (chú) reinforces the sense of 'removing' or 'eliminating', and 键 (jiàn) means 'key' (as in keyboard key). Together, they form a compound noun referring specifically to the physical or virtual button labeled 'Delete' (often abbreviated as 'Del') found on most input devices.

This term is widely used in everyday computing contexts — from typing documents and editing spreadsheets to managing files and clearing search history. While it’s sometimes confused with the backspace key (退格键), the delete key typically removes content *after* the cursor position (or selected items), whereas backspace deletes *before* the cursor. It's also commonly referenced in software instructions, tech support, and digital literacy education in Chinese-speaking environments.
